OK, one last hurdle and then I can fully manipulate the treeview on the client.  Deleting tree nodes.

As you can see below I cannot actually get the treenode to be removed from the treeview.  I think its because I am not getting a reference to the proper object and probably I am not using the right function to remove it.  Any input you can provide would be appreciated.

function CHAS_DeleteTrvNode(strTrvClientID, strParentID, strNodeID)
{
   //alert(strTrvClientID + ' , ' + strParentID + ' , ' + strNodeID);
   var oTree = dnn.controls.controls[strTrvClientID]; //obtain ref to dnntree 

   var oPNode = oTree.DOM.findNode('n', 'id', strParentID); //find the parent DNNNode
   if (oPNode != null)
   {
      var oPTNode = new dnn.controls.DNNTreeNode(oPNode); //Cast it to DNNTreeNode
      var oCNode = oTree.DOM.findNode('n', 'id', strNodeID); //find Child DNNNode
      if (oCNode != null)
      {
         var oCTNode = new dnn.controls.DNNTreeNode(oCNode); //Cast it to DNNTreeNode
         oPNode.removeChild(oCNode);
         oTree.update(); //update tree's xml so postback will persist
         var oPCtr = oTree.getChildControl(oPTNode.id, 'pctr'); //obtain ref the DIV Object
         var oCCtr = oTree.getChildControl(oCTNode.id, 'ctr'); //obtain ref the DIV Object

         document.removeChild(oCCtr);
         //oCCtr.remove;
         //alert(oTree + ' , ' + oCCtr);
         //oTree.removeChild(oCCtr);
       }
    }
}
